WELL-BORING AEPARATUS.

Application led June 1, 157222. Serial No. 56,5,13Q-5 Be it known that I, SIDNEYII. IjIUsTom citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in a fell-Boring Apparatus, of which thefollowing is a specilication.

This invention relates to new and useful improvements in a well boring apparatus. n

One object of the invention is to provide an apparatus of the character described especially designed for the purpose of assisting in the removal of the pipe that may become stuck in the well bore. In well drilling operations the pipe often becomes stuck in the bore to such an extent that the pipe willA be so securely stuck in the bore that it can not be pulled. It is one object of this invention to provide an auxiliary apparatus to be carried by the pipe whereby a fluid course, or fluid courses may be formed through the caved in formation so as to permit a return of the fluid forced down through the pipe and thereby the caved in formation may be gradually washed away so as to release and loosen the pipe to permit the same to be pulled from the bore. v

With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure l is a side View of one form of the device. y

Figure 2 is a side View of another form of the device.

Figure 3 isa transverse sectional view thereof taken on the line 33 of Figure 2.

Figure 4 is a vertical sectional view of another form of the device and,

Figure 5 is a transverse sectional View thereof taken on the line 5 5 of Figure 4.

In the drawings the numeral 1 designates the pipe in the bore. Suitable wires or cables as 2, 2, Figure 1, are arranged on each side of this pipe and their lower ends are secured to the lower end of the pipe and extend up through the bore to the ground surface. In the form shown in Figure 1 the lower ends of the wires or cables 2 are secured to the pipe by wrapping wire 3 therearound.

` In the forinshown in Figures 4 ,and 5 L., a single wire asv 4 is passed tlirougllQPPQi to the ground surface. In vcase the pipe-bef comes stuck an upward 'pull' is exerted on the wires or cables 2, or 4, these wires 2 and 4 are made weaker at their lower ends so that they will readily break in case an upward pull is exerted, and the wire 4 is made weak at the point 6 so that it will break in two in case an upward pull is exerted. Then these wires' or cables are oscillated or moved sideways or withdrawn they will leave open fluid courses up through the caved in formation and uid may then be forced downwardly through the pipe 1 and it will return through said water courses. As said water is forced under considerable pressure it will soon wear away and enlarge the iiuid courses by erosion and the caved in formation will gradually be partly or entirely washed out so as to loosen up the pipe to permit it to be withdrawn.

In Figure 2 I have shown a pair of 0ppositely disposed housings 7 7 which are secured to the lower end of the pipe in any preferred manner, preferably by wrapping wire 8 therearound. Within these housings are yieldable members as 9 or 10. The yieldable member 9 has its lower end attached to the lower end of the housing and to its upper end there is attached a wire or cable 11 which extends up alongside the pipe to the ground surface. The yieldable member 10 has its upper end secured to the upper end vof the housing and the wire or cable 12 has its lower end Vattached to the lower end ofl said yieldable member and it passes up alongside the pipe 1 to the ground surface. In case the pipe becomes stuck in the bore the wires or cables 11 and 12 may be pulled upwardly and released, and when released the members 9 and 10 will pull them back downwardly and this process may be repeated until a fluid course of considerable dimensions is formed through the surrounding material around the pipe and then the wires or cables 11 and l2 may be pulled upwardly until they break near their lower ends, said wires or cables being wekened at the point where they should break. They are then withdrawn and fluid forced under pressure down through the pipe 1 and this water returns through said Huid courses on the outside of the pipe and gradually erodes away the formation so asr to loosen up the pipe and permit'it to be withdrawn.V

What I claim is l. In well boring apparatus the combination'with a pipe of flexible members ou the outside of the pipe one on each side extending from nearthe bottom of the pipe up to the ground surface, said members being'awakened at or near their lowerends.

2. In well boring apparatus the combination with a pipe of a flexible member, 0n the outside of the pipe said member having a yieldable connection to the pipe near its name to this specification in the presence 25 of two subsoribingwitnesses. y
